This article discusses two areas at the intersection of social determinants of health research and social justice theory. The first section examines the affinity between social epidemiology and the capabilities approach. The second section examines how social epidemiology's expansion of the scope of the causal chain and determinants raises questions about epistemology and ontology in epidemiology as well as the field's link to the moral concern for human health.
